Sleeper odds API

Sleeper is a US DFS pick'em app. PropLine pulls its odds into one REST API for 17 competitions (MLB, WNBA, NFL, NHL, NCAAF, Golf, Tennis, UFC, Esports and 8 soccer leagues). Prices are pregame only: we stop polling a game once it starts. Filter to this book with bookmakers=sleeper.

No credit card. 1,000 requests / day on the free tier.

This list is generated from the sports we poll Sleeper for. A competition only returns Sleeper odds while the book has a board up for it, so an off-season league comes back empty. Pick'em lines are not sportsbook payouts, so they are left out of /ev and /best-line.

Drop bookmakers= to get every book in the same call, or pass several keys comma-separated. The response is the-odds-api compatible — events, bookmakers, markets, outcomes — so switching is usually a base URL change. Use markets=h2h,spreads,totals to pick markets.
